Hi.
On a Infineon XMC4700 Arm processor, i've activate the sector read/write protection with a password -> XMC_FLASH_InstallProtection(0, PROTECT_RP_WPS0, (uint32_t)PW1, (uint32_t)PW2);
Now I have no way to erase the whole chip.
The connection with JLink is ok, but if i try to unlock the device, JLink show's a error.
is there a way to delete the chip if i know the passwords?
Here the output from JLink:
J-Link>connect
